EBSILON®Professional – The Planning Tool for the Power Plant Process

EBSILON®Professional is a simulation system for thermodynamic cycle processes that is used for plant planning, design and optimization. Maximize the benefits of repowering and retrofitting measures by simulating them in EBSILON®Professional. Design a performance-optimized plant for your application scenario by introducing specific parameters into the model. Calculate the effects of component degradation, various load cases and changes in environmental conditions. Simulate the operation of newly developed components in a cycle.

Precise planning is the basis for a successful implementation of the project, both in the construction and in the modification of energy and power plant systems. It has to be analyzed early on whether and how the performance requirements can be achieved. EBSILON®Professional supports you in the planning, from the feasibility study right up to the detailed design of the plant.

Owing to the high flexibility of the system and the universality of the approach, any thermodynamic cycle can be modeled. From conventional power plants, nuclear and solar power plants right up to desalination plants, fuel cell applications as well as user-specific processes, there are no limits to the modeling options.

EbsBoiler – the Boiler in Detail

EbsSolar – We Make the Sun Calculable

EbsBoiler contains components for the detailed modeling of boiler geometry and heat transfer. Thus you map the boiler close to reality, model specific boiler types, and determine the degree of fouling of individual heating surfaces.

EbsSolar, developed in cooperation with the German Aerospace Center (DLR), contains components for the detailed dimensioning of a solar field. It is suited for investigations concerning site and technology as well as for annual return calculation. Regarding the simulation of the storage system, direct and indirect storage components are available. The indirect storage calculates the temporally variable temperature field of the storage material. The direct storage allows the modelling e.g. of a two-tank liquid salt storage. Typical heat transfer fluids like thermal oil, liquid salt, and water/steam are stored in the material data library.

EbsValidate – Data Validation

EbsHTML – Plant Model in the Web Browser

EbsValidate adjusts the partially error-prone measured values of the numerous measuring points of your plant in such a way that all component equations are complied with. At the same time the error sum of squares is minimized. The result is the statistically most likely plant condition. Here the use of redundant measured data increases the statistical reliability of the validation result. Besides a quick validation, validation according to VDI 2048 is available, too.

EbsHTML allows the output of the model including the simulation results in HTML format. The results for components and lines are displayed in a tool tip when the cursor is moved over them. Concerning the output you are free to decide which simulation results are to be displayed in the HTML file. G G

The offline validation with EbsValidate is suited for supporting acceptance tests, and for identifying malfunctions in the measuring system and the components. G
